Chris kindly shared the PDF above with us, that shows a Sony SRG series (VISCA) Camera connected to a Lifesize Icon 600 via the Sound Control Technologies RC4 Cat 5e/6 Extender solution. Per the diagram, all signal and camera control information is sent over the single Cat-5e/6 cable between the two SCT devices, eliminating the need for independent signal and VISCA extension cables.

Thanks again to Chris for providing this information, I'm sure many of our system integrators will find it useful.
